THIELE SMALL PARAMETERS
This speaker has Helicex technology, which gives:
- Higher power handling capacity. The thermal limit is effectively reduced, allowing the voice coil to work 80ºC below comparing to our previous thermal circuit.
- Reduced power compression losses, which allows to keep the final SPL (Sound Pressure Level) in more constant values within a working period.
- More stable and linear behaviour of the moving assembly in long excursions thanks to the new system design, reducing offset issues commonly related to asymmetries in non-linear components (mainly Bl(x), L(x) and Kms(x)).
- Dynamic response. The efficiency of the HELICEX® system allows to use 5” or 4” voice coil diameter (depending on model), which means lower Mms values and better control of the moving assembly compared to other systems and comparable products available nowadays, as well as lower overall weights of the speaker because of an optimized dimensioning of the mechanical assembly.
This speaker has PM4 technology
The new PM4 diaphragm, incorporates a new high tech polymer never used in audio before.
Delivers a stronger joint between the dome and the former of the voice coil and so a better behaviour with high power handling and long periods of working.
In the subjective field, which is also a relevant part in the Beyma development process, in our opinion it brings a more natural sound when comparing it with other polyesters.
MMSS Technology (Mechanical Mirror Suspension System)
Ideally the moving assembly behaviour must be the same in positive and negative excursions.
To provide this attribute correctly depends on the magnetic circuit design but also on the suspension system characteristics.
Our tool for achieving a symmetric movement pattern is the MMSS Technology, which provides to our engineers a complete set of components with their parameters in long excursion terms.
In Beyma we face the problem of heat dissipation with a clear goal in mind: the speaker must deliver the best performance in the system in a consistent and reliable way, maximizing the total SPL and keeping it stable.
It is well known how the overall SPL of a system suffers a drop after some time working due to the power compression effect in the speakers.
It is also known the bigger the voice coil diameter the lower the power compression and the higher the power capacity, but this also means bigger motor structures to obtain high sensitivity from the transducer.
The latest cooling technology that we deliver to the Professional Audio market through our new speakers, bring together several solutions to meet our goal; in one side allows the woofer to handle bigger rates of power with a given coil diameter, so we can think in smaller coil designs with smaller motor structure, reducing the weight but increasing the sensitivity and also keeping an adequate power handling figure for a target application.
Products like the 18PW1400Fe, 21PW1400Fe or the unique 12MC500 are designed following that concept; models that even with a ceramic magnet structure, feature high sensitivity, an increased power capacity and performance comparable to bigger coil designs with neodymium motor structures.
The increase of temperature in a pleated diaphragm strains every fold, limiting the electrical power it can handle.
The target of Xbow Technology is to open as much as possible the constraint in the diaphragm, allowing it to manage higher temperature rates and so increasing the limit of the power it can handle.
